Compiling a caseload index for mental health case management

Objective: The purpose of this study was to explore methods of determining an appropriate caseload for mental health case managers. Method: Seven factors that may impinge on case manager performance and impact on caseload were identified, having reference to published literature and service practice in Victoria and Queensland. The advantages and disadvantages of including these factors in a caseload index were evaluated. Results: Three caseload index methodologies are presented. Each method makes use of different data and has advantages and disadvantages. There is a trade-off between simplicity and ease of application and the comprehensive use of relevant information. Methods vary in their implications for service efficiency and equity in workload distribution. Conclusions: Caseload is a key issue in service planning and staff management. Factors that have the potential to contribute to caseload can be readily identified. However, there is likely to be disagreement as to the weight assigned to any factor and the approach taken may depend on the purpose and context of the caseload calculation. A great deal more research is required to provide an empirical basis for algorithms used in caseload calculation.

Sequence variation in the Newcastle disease virus genome

Full-length genome sequences of five virulent and five avirulent strains of Newcastle disease virus isolated between 1998 and 2002 in Victoria and New South Wales, Australia were determined. Comparisons between these strains revealed that coding sequence variability in the haemagglutinin-neuraminidase (HN), matrix (M) and phosphoprotein (P) gene sequences appeared to be more variable than in the fusion (F), nucleocapsid (N) and RNA dependent-RNA replicase (L) genes. Sequence analysis of a number of other isolates made during the recent virulent NDV outbreaks, also identified the presence of a number of variants with altered F gene cleavage sites, which resulted in altered biological properties of those viruses. Quasispecies analysis of a number of field isolates indicated the presence of virulent virus in one particular isolate. Gene sequence analysis of the progenitor virus isolated in 1998 showed very little sequence variation when compared to that of a progenitor-like virus isolated in 2001 demonstrating that in the field. viral genome sequence variation appears to be biologically restricted to that of a consensus sequence.

HETEROGENEIDADE EM REDE: PRESENÇA E PRÁTICAS DE USO ENTRE ESTUDANTES DA UNIVERSIDADE METODISTA DE SÃO PAULO NAS REDES SOCIAIS

As redes sociais pela internet ganham destaque nos processos comunicacionais atuais ao permitirem uma maior interação entre os conectados. Entretanto, o conceito de rede, ao contrário do senso comum e do que se convencionou no meio acadêmico, de fato não propõe uma organização simétrica, estática e homogênea. A rede é, por natureza, dinâmica e heterogênea, assim como a sociedade é. As redes sociais e as redes digitais demonstram isso. Elas aumentam e diminuem seus nós e possuem diferentes graus de conexões, e mesmo nestes graus de conexões são diversas. O presente estudo está dividido em duas partes fundamentais. A primeira visa compreender o conceito de rede, e para isso baseia-se em Milton Santos, Pierre Musso e Albert-Lásló Barabási. Na segunda parte, a partir de uma pesquisa com estudantes universitários, há a preocupação de identificar as heterogeneidades existentes nas suas presenças nas redes e suas práticas de uso, a partir de seis categorias de análise e atividades relacionadas: relações pessoais, estudo, trabalho, ativismo, entretenimento e lazer, e informações e notícias. A questão de fundo, a respeito das possibilidades das redes, é sobre os diferentes níveis de participação, ou seja, a heterogeneidade em rede. O resultado do estudo constata a heterogeneidade, na qual os estudantes, por mais que possuam semelhanças em função da idade aproximada, da condição social e pelo fato de estudarem em uma universidade particular, são diferentes entre si, em especial, se comparados pelas áreas de formação. Não só a presença nas redes sociais se dá em níveis diferentes, quanto suas práticas também são. Portanto, o conceito de redes heterogêneas contido no pensamento de Milton Santos, Pierre Musso e Albert-Lásló Barabási, é confirmado com a pesquisa aplicada aos estudantes universitários dos cursos de graduação presencial da Universidade Metodista de São Paulo, a partir da análise de suas presenças e práticas de uso.  

The social construction of lesbianism: a reappraisal

The commentators in this reappraisal describe The Social Construction of Lesbianism (1987) as ‘classic’ (Coyle1), ‘exciting’ (Tiefer), ‘important’, (MacBride-Stewart), ‘fascinating’ (Snelling), a ‘remarkable achievement’ (Snelling), and an ‘engagingly written, political tour de force’ (Coyle). Like some of the commentators (Coyle, Snelling), one of us (VC) owns a well-read copy of The Social Construction of Lesbianism, highlighted in all the colours of the rainbow and covered in (now) rather cryptic notes. This was the copy that passed back and forth between us as we completed our PhDs in lesbian and gay psychology, both of which were supervised by Celia Kitzinger. As young lesbian feminists, we were drawn to Celia’s radicalism and uncompromising political commitment. She was an inspiring, challenging, passionate and energetic PhD supervisor, and we are honoured and privileged to edit this reappraisal of The Social Construction of Lesbianism, a book based on her PhD.

Polymer fiber Bragg gratings

This chapter deals with gratings recorded in polymeric optical fibers (POFs); predominantly those based on poly (methyl methacrylate) (PMMA). We summarise the different mechanical and optical properties of POFs which are relevant to the application of POF Bragg gratings and discuss the existing literature on the subject of the UV photosensitivity of PMMA. The current state of the art in POF grating inscription is presented and we survey some of the emerging applications for these devices.

Linked data flows in multi-player games for servitisation

The increased data complexity and task interdependency associated with servitization represent significant barriers to its adoption. The outline of a business game is presented which demonstrates the increasing complexity of the management problem when moving through Base, Intermediate and Advanced levels of servitization. Linked data is proposed as an agile set of technologies, based on well established standards, for data exchange both in the game and more generally in supply chains.

Sensing presence (PreSense) ontology : user modelling in the semantic sensor web

Increasingly, people's digital identities are attached to, and expressed through, their mobile devices. At the same time digital sensors pervade smart environments in which people are immersed. This paper explores different perspectives in which users' modelling features can be expressed through the information obtained by their attached personal sensors. We introduce the PreSense Ontology, which is designed to assign meaning to sensors' observations in terms of user modelling features. We believe that the Sensing Presence ( PreSense ) Ontology is a first step toward the integration of user modelling and "smart environments". In order to motivate our work we present a scenario and demonstrate how the ontology could be applied in order to enable context-sensitive services. © 2012 Springer-Verlag.

An information foraging theory based user study of an adaptive user interaction framework for content-based image retrieval

This paper presents the design and results of a task-based user study, based on Information Foraging Theory, on a novel user interaction framework - uInteract - for content-based image retrieval (CBIR). The framework includes a four-factor user interaction model and an interactive interface. The user study involves three focused evaluations, 12 simulated real life search tasks with different complexity levels, 12 comparative systems and 50 subjects. Information Foraging Theory is applied to the user study design and the quantitative data analysis. The systematic findings have not only shown how effective and easy to use the uInteract framework is, but also illustrate the value of Information Foraging Theory for interpreting user interaction with CBIR. © 2011 Springer-Verlag Berlin Heidelberg.

Applying Information Foraging Theory to understand user interaction with content-based image retrieval

The paper proposes an ISE (Information goal, Search strategy, Evaluation threshold) user classification model based on Information Foraging Theory for understanding user interaction with content-based image retrieval (CBIR). The proposed model is verified by a multiple linear regression analysis based on 50 users' interaction features collected from a task-based user study of interactive CBIR systems. To our best knowledge, this is the first principled user classification model in CBIR verified by a formal and systematic qualitative analysis of extensive user interaction data. Copyright 2010 ACM.

A framework for evaluating semantic metadata

Because poor quality semantic metadata can destroy the effectiveness of semantic web technology by hampering applications from producing accurate results, it is important to have frameworks that support their evaluation. However, there is no such framework developedto date. In this context, we proposed i) an evaluation reference model, SemRef, which sketches some fundamental principles for evaluating semantic metadata, and ii) an evaluation framework, SemEval, which provides a set of instruments to support the detection of quality problems and the collection of quality metrics for these problems. A preliminary case study of SemEval shows encouraging results.

KnoFuss:a comprehensive architecture for knowledge fusion

We propose a knowledge fusion architecture KnoFuss based on the application of problem-solving methods technology, which allows methods for subtasks of the fusion process to be combined and the best methods to be selected, depending on the domain and task at hand.
